Description   The E3200 offers a large viewing surface of 21 x 26 cm to accommodate larger gels or multiple small gels.  High powered, 14-Watt UV bulbs provide higher sensitivity, so the smallest bands of stained nucleic acids can be visualized.  The E3200 also features a control knob for continuous adjustment of the UV intensity.   https://accuris-usa.com/Products/uv-transilluminator/
